[O] numbering figure in html ?

[Joseph Vidal-Rosset]

Hello everybody,

In org-mode exporting

\begin{figure}

\begin{tikzpicture}

\draw[<-, >=latex][thick] (0,0) -- (1.6,0) node[right] {Subcontrary};
...

end{tikzpicture}

\caption{Square of opposition}

\end{figure}

works well with LateX, but fails with html: each Figure has the same number, i.e. 1.

What is the best solution to get numbered Figure in html?

Regards

Jo.
